Please refer to our usage advisory for the short course vehicles. The short course trucks are too heavy for most 1/10th setups, so please don't blame the setup; all speed control manufacturer's are dealing with this problem. They need a bigger motor to push the weight of a short course vehicle. If you run a very conservative gearing (12/90) and lowest timing, it should work just fine. We do not recommend using the Sidewinder in that setup though, it will always run too hot.
We released the sidewinder and all of our 1/10th systems years ago, well before the short course trucks were released. We are trying to get as much info out as possible about this issue, but if you don't research your setup beforehand and follow our recommendations, then there's not much we can do.
Here is a link to the short course usage advisory.
